Last month, York University’s New Frontiers in Graduate History conference hosted a roundtable panel that explored the contributions of environmental history research. Panelists were asked to speak about their own experiences as environmental historians and to reflect on some of the origins of the sub-discipline, its scholarly and public history contributions, and its future prospects. The panelists included Sean Kheraj, Richard Hoffmann, Colin Coates, and Michael Egan. Each speaker discussed his own research and commented on the broader implications of environmental history research.
